first embodiment

[0013]FIG. 3 shows a block diagram for the present invention. Referring to FIG. 3, the first graphic processing unit 24a and the second graphic processing unit 24b, further include an overlay module 30a, a palette module 32a, an overlay module 30b, and a palette module 32b, respectively. The overlay module 30a mainly overlays the graphics for the backdrop and the graphics for the moving object racing car and converts it into an index color. The palette module 32a then converts the index color into a physical color which can be actually represented on the first display device 16.

[0014] If there is a need to display different graphics on dual display devices 16 and 17 for the live racing car scene and the racing car map, respectively, a first output router 34a selects the processed game backdrop graphics and the moving object graphics and put them onto the first display device 16. A fourth output router 34d selects the processed car racing map graphics as the backdrop graphics and the...

Abstract

The present invention provides a single-chip but multi-output graphic system which provides identical or different graphic images on two display screens. The graphic system comprises at least a multimedia database, a first input process router, a second input process router, a first graphic processing unit and a second graphic processing unit. The first input process router selects the backdrop graphics and the moving object graphics (which are both provided by the multimedia database), feeds them into the first graphic processing unit and then outputs the processed graphics onto either the first display unit or the second display unit. Similarly, the second graphic processing units processes the backdrop graphics and the moving object graphics selected by the second input process router and then outputs the process graphics onto either the first display unit or the second display unit.

Description

FIELD OF THE INVENTION [0001] The present invention generally relates to a graphics processing system, and more specifically to a single-chip multi-output graphic system. BACKGROUND OF THE INVENTION [0002] Nintendo Dual Screen (DNS) is a new generation handheld game device introduced by the Nintendo Japan Co. Ltd. The main feature of this new product is its dual display facilities. With the advantage of the dual displays, game manufactures can thus provide more exciting varieties of games with improved convenience. [0003] Taking a racing car game as an example, with the dual screen capability, one display can be used for the 3-D backdrops with the player's racing car; while the other display can show a map with the player's racing car position indicated. This provides players the dual views with not only the vivid 3-D gaming scenes, but also the wider and clearer perspective of the map for car racing. [0004]FIG. 1 is a schematic view of a conventional graphic system. Referring to FI...
